construction of a waste-water pocket, au in-` Y duction-nozzle, and adischarge-nozzle by casti .y ing thein on oneof the plates constituting the a casing which incloses the wheel; second,`form i ing in the centerof each casing-plate an annu-` l lar internal depression surrounding an eX- tended wheel-shaft hearing; thrd,-castinga bracket-extension on the external side of one @i of the plates of the wheel-casing, whichshall serve not only for attaching' the motor` onto ,1 fthe top of a sewing-machine table, but at its `upper end form a bearing for the motor-shaft; a y fourth, the employment of adrip-pan beneath 1 i, thepedaI-cOck, constructed 'so as to serve not y only the purpose of a drippan,but also asa "support for the water-cock and treadle; lifth, 1 the application of a detachable strainer-vessel ."toj the water-supply pipe at a point between theinjecting-nozaleand thetreadle-cockmhich vessel is` of an" enlarged capacityascompared a with @the diameter of the supply-pipeto which itis attached.

The following description ofniyinvention will enable others skilled inthe arttounderv stand it.

The wheel-case, whichIhavereprcsentedini` f1 .i the annexed drawings,lconsistsofg-twocasta;` l y ings, A and A, of circular forni, `whichare.:` l l bolted together, as shown inFigs.l2,l3, land 8,1 u so as to forni a chamberfor the waterwheel.` B,and a receptacle for receiving and;discharg-i` ing the waste water.` llie l plate A is con-1 structed with an annular `depression,por, fort` l receivingthe outer bucketcarrying portion of.` `l y the wheel, and also witha central annular. de#` pression, e, which latter surrounds a lolngibearing, j,1`or the wheel-shaft@` Thelower portion` j 1j. of this plate Ais constructed with anupWal'dly` Haring pocket, A2,of,less widththan thewidth M i of the casing, taken throughthe annulanspace l. f o, but of a length nearly equalto onethird the., circumference of the casing... The bottom of this pocket convergesto. a dischargenozzle, g,to which a waste-watenpipe,` P",-is suitably a" secured. At one end ofithepoclret A? anothen` nozzle, g, is formed, to whicha `inely-Uperfo-z Y rated nozzle, P1, isapplied, towhich nozzlethe;` i i; watcrinlet-pipePis secured..(ShwninFigs; f l and 8.) On the outside oftheplatelAlbelow V the shaft-bearingj, is ariglit-angularllatextenf 11 a sion, A3, which is the bracket through` which i screws are passed for securing themotonto the .1 a a table-topSof asewing-machineThisbraclct is formed homogeneous with the plateA,and z" 1 during the act of casting the plate, and is soV a constructedthat, while itlservesithe `purpose y of securing themotor tothe table-top, ,it `also 1 forms a part of one of the long bearingsj, for the wheelshaft c.

The pocket A2, the two nozzles gig', andthe .i bracket A3, arevallcast with, and forma part 1 i "1* of, `the plate A. The plate A1V has neithera a y bracket nor apocketformed onit.`` 11n [other .i i .i respects it is like theplateA-thatis,tosay, f i ithas an annular depresson,a,acentraldefi` i. pression, e, and an extended hub .orbearing,` l .a ff

a Marzo j. When the two plates A A1 are bolted together an annular laterally-enlarged chamber, 0, is formed for the bucket-carrying portion of the wheelB, andan annularlaterally-extended chamber, m, for receiving eye-brows7 or water-sheds d d. This chamber it will be seen surrounds the shaft c and its bearings j, and its concavity is such that any drip-water flowing down the inner face of plate A or over the eyebrows77 d d will be conveyed past and below the wheel-shaft c without escaping from the wheel-case between the bearing j and said shaft. By forming this central chamber m, that portion of the wheel-case between it can be contracted laterally, as shown-in Fig. 2, and besides this the bearings jj can be made of the proper length for affording good steady supports for the wheelshaft c without occupying more space later` ally than is occupied by the width of the wheel-case, as illustrated by Fig. 2. be seen by reference to Fig. l that the buckets z' of the wheel B are successively struck by a minute stream of water from the nozzle P1, which stream is directed downward and inward in a line which is tangent to a circle within the circumference of the wheel, thus utilizing the percussive force of the stream to drive the wheel. Now, in order to prevent the water from reacting or backing77 upon the buckets and retarding the speed or momentum of the wheel, the pocket commences directly beneath the said injecting-nozzle Pland terminates at a point opposite this nozzle or a little above it. A pocket thus constructed will catch all the water which falls from the buckets and conduct it directly down to the discharge-pipe P2. The wheel-case is secured onto the table-top of a sewing-machine by means of the bracket A3, as above slated, and the shaft c of the wheel B is connected to the driving-shaft Y of asewingmachine by eX- tending said wheelshaft and making it of two parts, which are coupled by means of two lapped half dovetails, s1, and a sliding tube or collar, s, the latter being held in place by means of an india-rubber tube, s2. That portion of the wheel-shaft c which is connected to the driving-shaft of the sewing-machine has a male screw, s3, formed on it, which is tapped into a screw-socket made into the end of the sewing-machine shaft Y.

Fig. 4, Plate 2, shows clearly the improved coupling and uncoupling device. It is made by simply beveling and shouldering the ends of two sections of the shaft c, slipping the Vtube s over these ends when lapped, Yand ad-V justing the india-rubber tube s up to its place against the tube s, thus making a simple and cheap coupling and uncoupling, and one which any lady can manipulate conveniently. By slipping the tube s off the lappedjoint s1, the motor is disconnected from the sewingmachine, and either or both machines can be detached from the tabletop. The wheel which is represented in the annexed drawings, but not herein claimed, is composed of two plates,

It will which are each struck up and secured together, as shown in Figs. l and 2, so as to form two iiaring flanges, r a", for receiving between them the buckets i, and also an internal stiffening-rib, if'. This bucket-receiving portieri of. the wheel is connected, by wire spokes b, to a hub, b', which is secured to the wheel-shaft c. I thus obtain a very light wheel, which possesses great strength and durability, and which is not liable to warp out of its truism. I prefer this construction of water-whee1 for my motor; but wheels which are constructed differently may be used with the improvements herein claimed. On the extended portion of thc wheelshaft c, between the motor and the driving-shaft of the sewing-machine, I secure a small wheel, n, beneath which is the frictional end of a brakelever, B, which is pivoted to a plate that is secured fast upon the table-top S, as shown in Fig. 8. By means of this brake an attendant at a sewing-machine can quickly check its speed. .Y

For the purpose of starting and stopping the machine, a single way -,cock, L, is used, through which water passes on its way from the service-pipes to the wheel-case. This cock is located on the door, beneath the table of the sewing-machine, in a convenient position to the feet of the operator, and it is mounted upon standardsf, which rise from a drip-pan, F. The plug h of the cock is extended, so as to form a support for a pedal or foot-lever, T, which is secured to it, and by means of which an operator can let on or cut off the fiow of water, and also regulate the flow at will. The drip-pan F is of such size that it will catch any water which might leak from the cock, plug, or the joint connection thereof, and thus protect a carpet from wet. Between the cock L and the nozzlednjector I, I apply to the pipe I a vessel, N, made of two detachable parts, and containing a perforated diaphragm. t, the object of which is to prevent small fish and foreign substances in the water from choking up the nozzle P1. By making the vessel N of two detachable parts, as shown by Fig. 7, it can be safely removed and cleaned when it becomes foul on simply closing the cock L; and hence I apply this device between the cock and the motor, and so avoid the trouble of cutting off the iiow of water to the cock L while in the act of removing and cleaning said vessel.

Having described my invention, what I claim as new, and desire to secure by Letters Patent, is-

l. The single casing-plate A, having an inductionnozzle, a waste-water pocket, and a discharge-nozzle formed thereon, substantially as and for the purpose described.

2. The annular chamber m, between plates A A1, surrounding the elongated bearings for the wheel-shaft c, substantially as described.

3. rIhe bracket extension A3, cast on the plate A, below the wheel-shaft c, so as to serve not only as a bracket, but at its upper end f form a `bearing for the motor-shaft c,"substan Lialjly `as described.
